My DSL Won't Connect
Your DSL service has been turned on, but you are unable to connect to the Internet. Your problem is probably one of two things: Either your computer is not connecting with the modem/router or your modem/router is not connecting with your phone service provider. Before you call a friend or family member over to help you fix your DSL connection there are a few system checks you can make to avoid wasting anybody's time.
Restart your computer. When working on computers one of the simplest methods of troubleshooting is to shut down your computer and restart it. The process of reconnecting is often all the computer needs to reset connections.
Turn off your DSL router, wait a minute and turn it back on. Occasionally the router needs to "re-synchronize the DSL signal and the network connection to your computer," according to the Hubris Communications website.
Check the power and phone cords on the DSL router to ensure they are plugged into the power outlet, router, phone jack and the computer. Jiggle them a little bit; if you have a short in one of the cords the movement could make the wire reconnect.
Put phone filters on any electronic item that taps into your phone service except the router. Left unfiltered, those devices could interfere with the DSL signal.
Check your firewall settings to see if they are preventing the DSL service from connecting. Click the "Start" button, then click the "Control Panel" link. A window will pop up. Select the "Security" and then the "Turn Windows Firewall on or off" options. Another pop-up window will appear. Click the circle next to the word "Off" to disable your firewall. Turn your router off, wait a minute and restart it. If your DSL connection is made, go to the "Security" window and click the "Allow a program through Windows Firewall." You will be redirected to another window where you will need to select your DSL program from a compiled list. If turning off your firewall makes no difference, turn it back on.
Contact your DSL provider's customer service. Providers will be able to check your phone line to see if there is an outside technical issue preventing your DSL from connecting.
